Preparing Mower For Storage

1. For long term storage, either drain gasoline from fuel
tank or add a fuel additive to the gasoline. To drain
gasoline, refer to Draining Gasoline. After fuel is
drained, start engine and let it idle until all fuel is
consumed and engine stops. If gasoline is not drained,
gum–like varnish deposits will form and cause poor
engine operation, even starting problems.
Fuel can be left in gas tank only if a fuel stabilizer,
such as Toro's Stabilizer/Conditioner, is added to
gasoline before storing. Toro's Stabilizer/Conditioner
is a petroleum distillate based stabilizer/conditioner.
Toro does not recommend stabilizers with an alcohol
base, such as ethanol, methanol or isopropyl. Use fuel
stabilizer in recommended quantities as specified on
container.
Under normal conditions, fuel stabilizers remain
effective in fuel for 6–8 months.
2. Remove spark plug and pour 2 teaspoons of Toro
Two–Cycle Oil into hole in cylinder. Pull starter rope
slowly to coat inside of cylinder. Install spark plug and
tighten to 13.6 N m (10 ft–lb). DO NOT
REINSTALL WIRE ON SPARK PLUG.
3. Clean underside of housing: refer to Cleaning Mower
Housing, Discharge Tunnel, Belt Cover and Plug.
4. Check condition of blade: refer to
Inspecting/Removing/Sharpening Blade.
5. Tighten all nuts, bolts, and screws.
6. Clean dirt and chaff from cylinder, cylinder head fins,
and blower housing. Also remove grass clippings, dirt,
and grime from external parts of the engine,
shrouding, and top of mower housing.
7. Clean air cleaner: refer to Servicing Air Cleaner.
8. Lubricate the pivot arms: refer to Lubrication.
9. Touch up all rusted or chipped paint surfaces. Toro
Re–Kote paint is available from an Authorized TORO
Service Dealer.
10. Store mower in a clean, dry place, out of the reach of
children. Cover mower to keep it clean and protected.
